WebFigure 1. Titration of 25.0 mL of 0.1M HCl by 0.1 M NaOH. Blocked areas on the curve indicate the pH range in which phenolphthalein and methyl red change colors. Note that the slope, ΔpH/ΔV, becomes large when the volume of NaOH added is at 25 mL, so this is the equivalence point. Because of this rapid rise through a range of pH values when WebThe volume of NaOH solution required to react with a known weight of KHP is determined by titration. Since 1 mole of NaOH reacts with 1 mole of KHP, the concentration of NaOH can be calculated. mass of KHP MW of KHP = moles of KHP. Moles of KHP = moles of NaOH (1:1 stoichiometry) moles of NaOH volume of NaOH in L = Molarity of NaOH (moles / L)
